Frost dates for Barnstable Town, MA, ZIP 02670

Zone 7b

Typically, the last spring freeze lands around 04/13, roughly 228 days out. The first fall frost typically arrives around 11/03, about 204 frost-free days later.

Zone 7b (5 to 10°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Barnstable Town, not a forecast for this year.

What to do before the first frost

Zone 7b around Barnstable Town has about 10 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.

Why 04/13 isn't a guarantee

04/13 is the middle of 30 years of NOAA records, not a promise. Plant by 04/02 and you're betting against frost in roughly 9 years out of 10. 04/26 is the safer bet, historically only a 1-in-10 chance of frost that late.
